Structural study of strontium aluminosilicate glasses and melts
The aim of this proposal is to study the structure of strontium aluminosilicates SrO-Al2O3-SiO2 (SAS) in both the glassy and liquid states. This study will extend the previous work performed at the ILL on the CaO-Al2O3-SiO2 system and will help to better understand the formation of aluminosilicates glasses, widely used in the glass industry. In particular, structural information derived from the pair-distribution functions (distances, coordination numbers) will be useful for understanding the mechanism of glass formation in these systems. For this experiment, we will use the levitation setup developed by the CEMHTI (Orleans) and integrated into the D4c diffractometer. These experiments will be complemented by X-ray diffraction and absorption (EXAFS) measurements, and Molecular Dynamics simulations will also be performed in collaboration with the ILL's computing group (C-lab).
